CoPe Conference: Evaluating Land Use Tradeoffs Due to Sea Level Rise in the Chesapeake Bay: Hampton, Va - June 2020/ Salisbury, MD - October 2020

切萨皮克湾（CB）沿海地区是美国海平面上升速度最快的地区之一。家园、生态系统和价值数百万美元的关键基础设施越来越面临侵蚀和各种洪水的风险。为了让CB社区规划未来，成员必须了解当地的海平面上升率（RSLR）以及导致这些当地变化的因素。RSLR差异的一个重要因素是CB周围的土地以不同的速度下沉（即垂直运动（VLM）），但这些速度背后的原因不容易测量或广泛理解。科学家，城市规划者和土地管理者必须讨论VLM的当前科学，如何监测其在CB的速率，以及可能的缓解策略。此外，科学家和广泛的社区利益相关者，包括那些代表性不足的农村地区，应该了解RSLR将如何对居民社区，湿地和农业产生多重影响。他们每个人都有自己的优先事项，这将影响什么样的管理选择是最生态，社会和经济可取或可行的。介绍最新的科学对RSLR的原因，预期的土地利用变化，以及不同的管理方案的成本效益将授权CB地区和其他面临类似威胁RSLR。该小组将召开两个研讨会：1）垂直土地运动在切萨皮克湾，和2）评估土地利用权衡在切萨皮克湾。研讨会1将提高对CB中VLM率物理驱动因素的科学理解，并确定了解VLM率可能对土地利用规划最为关键的领域。研讨会2将重点讨论如何有效地传播VLM科学，以及RSLR率如何导致土地利用变化并影响沿海社区。研讨会的目标是：1）了解和传播VLM的科学状态; 2）提高利益相关者对加速RSLR的理解; 3）了解RSLR如何改变当前的土地使用实践，以及4）在整个研讨会过程中吸引利益相关者。讲习班的日程安排包括：（a）讲习班前规划; B）举办研讨会1（c）研讨会1的综合和成果分析;（d）举办研讨会2;（e）综合报告和信息分发。与会者将包括研究人员、土地保护主义者、农业专家、城镇规划者和社区成员，特别是来自服务不足社区的成员。在这些讲习班结束时，将有更好的信息用于社区决策。研讨会组织者将评估利益相关者之间的优先事项如何不同，以及哪些因素最影响利益相关者的行动，这将指导选择研究，工具和外展社区需要有效地规划海平面上升。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Chesapeake Bay (CB) coastal region has one of the highest rates of sea level rise in the United States. Homes, ecosystems, and millions of dollars of critical infrastructure are increasingly at risk of erosion,and various types of flooding. In order for CB communities to plan for the future, members must understand their local rates of sea level rise (RSLR) and the factors contributing to these local variations. A significant contributor to differences in RSLR is that land surrounding the CB is sinking (i.e. verticalland motion (VLM)) at different rates, but the causes behind these rates are not easily measured or widely understood. Scientists, town planners, and land managers must discuss the current science of VLM, how to monitor its rates across the CB, and possible mitigation strategies. Furthermore, scientists and a wide range of community stakeholders, including those in underrepresented rural areas, should understand how RSLR will have multiple impacts on residential communities, wetlands, and agriculture. They each have their own priorities that will influence what management options are most ecologically, socially, and economically desirable or feasible. Presenting the latest science on the causes of RSLR, anticipated land use changes, and the cost-effectiveness of different management options will empower the CB region and others facing similar threats from RSLR.The team will convene two workshops: 1) Vertical Land Motion in the Chesapeake Bay, and 2) Evaluating Land Use Tradeoffs in the Chesapeake Bay. Workshop 1 will improve scientific understanding of the physical drivers of VLM rates in the CB and identify areas where understanding VLM rates may be most critical for land use planning. Workshop 2 will focus on how to effectively communicate VLM science and how rates of RSLR will cause land use changes and affect coastal communities. The goals of the workshops are to: 1) understand and disseminate the state of the science on VLM; 2) improve stakeholder understanding of accelerated RSLR; 3) learn how RSLR may change current land use practices, and 4)engage stakeholders throughout the workshop process. The workshop schedules involve: a) pre-workshop planning; b) holding workshop 1 c) workshop 1 synthesis and outcomes analysis; d) holding workshop 2; and e) a synthesis report and information distribution. Participants will include researchers, land conservationists, agricultural specialists, town planners, and community members, especially from underserved communities. At the end of these workshops there will be better information for use in community decision-making. Workshop organizers will assess how priorities differ among stakeholders and what factors most influence stakeholders' actions, which will guide selection of the research, tools, and outreach communities need to effectively plan for sea level rise.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
